RIYADH, Oct. 27 (CGTN) -- Saudi Arabia will prosecute the suspects in the killing of journalist Jamal Khashoggi, Riyadh's foreign minister said on Saturday in response to a call by Turkey for their extradition.

"On the issue of extradition, the individuals are Saudi nationals. They're detained in Saudi Arabia, and the investigation is in Saudi Arabia, and they will be prosecuted in Saudi Arabia," Foreign Minister Adel al-Jubeir said at a regional defense forum in the Bahraini capital.

Jubeir's comments came the day after Turkish President Recep Tayyip Erdogan called for the extradition of 18 Saudi nationals authorities say were involved in the murder of Jamal Khashoggi, a Saudi government critic killed in Saudi consulate in Istanbul this month.

After denying knowledge of Khashoggi's whereabouts for nearly three weeks, Riyadh admitted he was killed and his murder had been "premeditated", but denied any involvement of Crown Prince Mohammed bin Salman.
